Uyini umehluko phakathi kwe-magnesium oxide ne-magnesium carbonate?

I-Magnesium oxidefuthii-magnesium carbonateziyahlukahluka ezintweni zazo zamakhemikhali.I-Magnesium carbonatei-asidi ebuthakathaka encibilika emanzini bese ihlukana ibe i-magnesium oxide ne-carbon dioxide lapho ishiswa.I-Magnesium oxide, ngakolunye uhlangothi, iyi-alkaline oxide engancibiliki emanzini futhi ayiboli lapho ishiswa.

Imboni yesicelo kanye nezici zomkhiqizo we-magnesium carbonate ne-magnesium oxide zihlukile ngale ndlela elandelayo: Imboni yohlelo lokusebenza: I-Magnesium carbonate isetshenziswa kakhulu emikhakheni yemithi, i-antacid, i-desiccant, i-ejenti yokuvikela umbala, umthwali, i-anti-coagulation agent nokunye;Ekudleni njengesengezo, i-ejenti yesinxephezelo sesici se-magnesium;Embonini yamakhemikhali emihle yokukhiqiza ama-reagents amakhemikhali;Isetshenziswa njenge-ejenti yokuqinisa kanye ne-filler ku-rubber;Ingasetshenziswa njenge-insulation yokushisa, izinto zokushisa eziphakeme eziphikisana nomlilo;Inqubo yokukhiqiza intambo nekhebula ezibalulekile izinto zokusetshenziswa zamakhemikhali, njll. Magnesium oxide isetshenziswa ikakhulukazi ku-silicon steel, i-catalyst, imboni yezemithi, imboni yokudla, izinto zokusetshenziswa zezimonyo, izithasiselo zepulasitiki, izithasiselo zenjoloba, izinto ze-electrode, izinto ze-glass substrate kanye neminye imikhakha.Izici zomkhiqizo: I-Magnesium carbonate iyikristalu esobala engenambala, i-alkaline, inyibilika emanzini, i-alkaline kancane;I-Magnesium oxide, ngakolunye uhlangothi, iyimpushana emhlophe, i-alkaline futhi ayincibiliki emanzini.

I-Magnesium carbonate ihlukaniswa ngale ndlela elandelayo:

I-magnesium carbonate ekhanyayo: i-white brittle noma impushana emhlophe exegayo, ayinaphunga, izinzile emoyeni.Uma ishisa kufika ku-700 ° C, iyabola ukuze ikhiqize i-magnesium oxide, i-carbon dioxide namanzi.Emazingeni okushisa asekamelweni, ingusawoti we-trihydrate.I-magnesium carbonate esindayo: impushana emhlophe, ayinambitheki, ayincibiliki emanzini, ishiselwa ukubola okungaphezu kuka-150℃, ukukhiqiza i-magnesium oxide ne-carbon dioxide.Ezingeni lokushisa legumbi, ingusawoti we-hexahydrate.

Ukuhlukaniswa kwe-magnesium oxide imi kanje:

I-magnesium oxide ekhanyayo: ifomula yamangqamuzana i-MgO, ukubukeka kumhlophe noma i-beige powder ekhanyayo, ayinaphunga futhi ayinambitheki.Uma uchayeka emoyeni, kulula ukumunca amanzi ne-carbon dioxide, engancibiliki emanzini notshwala, futhi inyibilika kuma-acid ancibilikayo.I-magnesium oxide esebenzayo: ukusetshenziswa kancane, okusetshenziselwa ukugcwalisa irabha ye-neoprene, ukuqinisa futhi njengesisusa.I-magnesium oxide enzima: Ifomula ye-molecular MgO, ukubukeka kwempushana emhlophe, engenaphunga, engancibiliki emanzini.Uma ishiswe ngaphezu kuka-1500 ℃, iba yi-magnesium oxide eshile (i-magnesia) noma i-sintered magnesium oxide.
